To all whom it may concern:

Be it known that I, WILHELMUS ADRIANUS vaN BERKEL, a subject of the Queen of the Netherlands, residing at Rotterdam, Kingdom of the Netherlands, Boezemsingel 56, have invented certain new and useful Im' rovements in Slicing-Machines, of which the ollowing is a specification.

This invention relates to improvements in slicing machines having a rotary circular 1 knife, to an improved arrangement of the tooth piece for moving forward the plate on which the piece of meat' is clamped, and also to a s ring mounting of this plate in conncction t erewith.

These improvements have for their object:-1. To rovide a tooth'piece which may be broug tm asimple manner into and out of enga ement wit 1 the screw of the shifting 'mec ianism. 2. To give the meat plate a spring mounting so that the )lay in the screw of the shifting: device and. a so the slight Wear and tear of the plate may be automatically compensated for.

A meat slicing machine provided with these improvements is shown in the accompanying drawings, in which,

Figure 1 is a cross section; Fig. 2, a plan view of the table; Fi 3 and 4, sections on an enlarged scale of t e s ring mounting and the new tooth piece fort 1e shiftin mechanism respectively. Fig. 5 is an en arged detail elevation of a portionof the meat-holding plate and the tooth-feeding piece showing a part of the feeding screw in dotted The shifting mechanism which provides that the meat plate ais each time moved forward to the thickness of a slice, is ar:- ranged'at the side of the table and fined above on this table. The meat plate a lies quite free between lateral guide bars c cn the table b. Y

To the u side of the plate a near one end thereo 1s attached a tooth-piece d having teeth adapted to mesh with the threads ofascreweoftheshiftingmechanismsothat `when the screw e is turned in the direction indicated by the arrow the plate a is caused to move toward the knife u shown Vdiagramxnatically in Fig. 1. Y

As it would require too much time to bring the piece of meat o posite the kniie by turning the screw spin e e, or by lifting the meat plate a off the table b and again placing it in the desired position, a mechanism is adopted by means of which the tooth piece d may be brou ht out of eng ement with the screw spin e e, the meat p ate a being adapted to be moved freel to and fro on the table. For this object t e tooth piece dis made pivotal on a point on themeat table a and provided with a andle g (Figs. 2 and 4) by means of which it may be brought either into the position I in engagement with the screw spindle e, or into the position II out of enga ement with said screw spindle (Fig. 4).-

n order to maintain the tooth iece m .one of the two positions,'a lock pin havin an oblique edge is provided on the tooth piece.

This pin is pressed outwards by means ofspiral spring .i and on the plate a a fixed stud c is provided. The lock pin h may be easily pressed back against this stud lc by ushin the tooth piece sidewise by the hand e g an the sameis then held in this position by the pin hresting on a fiat part of the studi: (Fig. 4).

By means of the handles l the plate a and the piece of meat s and the clamping device p g r may be reel displaced on the table b, or removed from t e same.

The spring action of the locking pin against the fixed stud k presses the tooth piece to the right and in this way assists its engagement in the screw thread of the spindle e. In order that any lay in the tooth piece d may not make itse f felt, a bar 1n is provided on the right hand guide bar c, which bar m is held by two screws n and pressed against the toothed bar p of the clam ,ing device by means of spiral springs o. T le pressure produced b the bar m allows of the movement of the p ate a in one direction and prevents undue play.

A projection t is provided on the end of the bar m which projection limits the movement of the plate a. At the same time in this arrangement an automatic adjustment of the plate a between the guide bars c is obtained when by reason of Wear the guidance between these bars is less exact.

I declare that what I claim is 1. In a meat slicing machine of the class set forth, a table, a meat plate slidably mounted n the table, a screw spindle dis- 10;

posed'at one side of the table, A. tooth piece pivotally carried by and movable over the plate for engagin the screw spindle, and a rcsilientlrv control ed locking means disposed longitudinally in the tooth piece and terminal projecting from the rear extremty of the atte: to cooperate witha portion the pl ate, the locking means being movable with the tooth'piece.

2. In a meat slicing machine of the claas? set forth, a table, a meat plate .slidably mounted on the table, a screw-spindle held at one side of the table, a tooth-piece ivoted at one end of the plate and normally eld in en` gagement with the screw-spindle, said tooth piece having one end free for adjustment and provided with locking means, and resiliently controlled means held by the table and engaging a portion of the plate to compensate or wear of the spindle and the toothiece.

3. In a meat slicing machine of t e class set forth, a table, a meat plate slidably.

mounted on the table, a screw spindle disposed at one side of the table,-a tooth piece pivotally connected at its forward extremity to the table and having a longitudinally extending locking pin therein and projecting from the rear extremity thereof, the tooth piece also having a toothed projection normally held in engagement with the screw spindle and a rearwardly extending handle adjacent to the rear terminal of the locking pin, and a projecting device on one side of the plate with which the said locking pin engages.

4. In a meat slicing machine of the class set forth, a table, a meat plate slidably mounted on said table, a screw spindle disposed at one side of the table, means pivotally carried by and movable over the plate for engagin the screw spindle, and 'resiliently-contro led means held by the table and enga ing a portion' of the plate to compensate or Wear of the spindle and the aforesaid means.

5. In a meat slicing machine .of the class set forth, a table, a meat plate slidably mounted on said table, a screw-spindle disposed at one side of the table, a tooth piece pivotally secured to and movable horizontally over the plate and normally held in enagernent with the spindle, said tooth piece avinor means for moving the same, a locking in held by the tooth piece ad'aeent to the ree extremity of the latter and aving a projecting head, a stud on the table a ainst which said head has bearing, and resiliently controlled means held by the table for compensating for wear and taking up play bef tween the spindle and tooth piece.

6. In a meat slicing machine of the class set forth, a table, a meat plate slidably mounted on the table, a screw spindle disposed at ,one side of the table, a tooth piece pivotally connected at one end to and movable horizontally over one side of the plate and normally held in engagementl with the screw spindle, the opposite end of the tooth piece being free for movement, a lock pin disposed in the free end of the tooth piece, a fixed stud carried by the plate for engagement with the said lock pin, and means carried` by the table for compensating for pla and Wear between the spindle and the tooth piece.

7. In a meat slicing machine of the class set forth, a table, a vmeat plate slidably mounted on the table, a screw spindle arranged at one side of the table a toothed means pivotally mounted on and movabie with the plate and held in engagement with the screw spindle during the feeding movement of the plate, an u standing bar secured to one side of the tab e near one end, and resilient devices enga ing a portion of the said'bar to permit the atter to yield, the bar havin bearing'against one side of the plate.

8` n slicing machines, the combination with the rotary knife and its driving mechanism, of a supporting slide having means for clam ing the meat thereto, guides wherein said s ide is mounted, feed mechanism for said slide, and an upright spring held frame at one of the side edges of the slide, and arranged to pressthe same laterally against its guide to automaticall take up lateral play and wear, substantia y as described.

9. In slicing machines, the combination withthe knife, the travelin carriage and drive mechanism for said kni e and carriage, of a su porting slide for the material moving in gui es on said carriage, and a spring device interposed between said carriage and slide and pressing said slide laterally to automatically take up loose pla and wear between said parts, substantie y as described.

10.
